It is of course safe to use one's own ear cartilage for rhinoplasty, just search the book, but usually ear cartilage is used for nose tip plastic surgery or needs to be wrapped with fascia tissue to improve the shape of the nose. Generally, the ear cartilage is taken from the concha cavity and concha concha, and can be taken out in a single piece, with an area of 2.8 1.5cm (close to the size of the thumb nail cover). But not every beauty seeker needs to take so much, and doctors need to calculate the amount of auricular cartilage needed for surgery according to the face-to-face diagnosis. For example, the nasal tip condition is good and the amount of ear cartilage needed is small; The tip of the nose likes to do three-dimensional exaggeration, and the amount of ear cartilage is more. Ear cartilage can also be easily carved into the required size and shape, and then it is a better material in terms of shape and safety. Ear cartilage belongs to elastic cartilage, which can curl and rebound and has a real touch. So you don't have to worry about normal contact with your nose after rhinoplasty with auricular cartilage. You can push your nose. It feels soft and lifelike. Generally speaking, the operation of auricular cartilage rhinoplasty is simple and easy to obtain from itself. It has low requirements for surgical instruments, low absorption rate of autologous cartilage and no rejection with human body, so it is a relatively safe rhinoplasty material.
